The Santiam Canyon School District in Mill City, Oregon faced aging facilities that no longer accommodated its growing student population. The rural district needed innovative ways to make multiple improvements and add square footage with quality construction, while holding to a tight budget. The district set out to build a new junior/senior high school, add an elementary school cafeteria, add a gymnasium and make site improvement to a growing rural school district in a short timeframe. By using Modern Building Systems’ factory-built components and CLT, the district was able to save money because a significant amount of labor was done off-site, saving on costs and allowing for quicker construction. The project showcases CLT throughout the construction, including beams, columns, roofs and walls. To complete the Santiam Elementary servery (cafeteria) walls, it took 3,500 sq. feet of CLT and 23,000 sq. ft. of CLT to create the Santiam Junior/Senior High School gym walls, roof, beams and columns. From an engineering standpoint, a challenge with this project was achieving a 72’ beam span to support the gymnasium roof. A steel plate splice in the CLT beam, engineered by ZCS Engineering, was the solution.
